Hey, I also have a 2015 Edge Titanium and i had the same issue with my actuator. I read in here that if you unplug it behind the gas pedal it could reset. I took mine to Brakes Plus and they tried the reset and it didn't work so they ordered a new actuator and for around $200 I no whave windshield defrost and it changes when you swithc to AC. Hope this helps.
